SOCHI - Two Russian activists, including one who has already been picked up twice in the last two weeks, were detained on the final day of the Sochi Olympics, their attorney said.

David Khakim and Olga Noskovets will be held for a minimum of 48 hours, Alexander Popkov told USA TODAY Sports on Sunday. They are to appear in court Monday and could be detained for up to 15 days.

Khakim was treated rudely when police took him to the station, Popkov said, and plans a hunger strike because of his treatment.

Khakim, who was picked up along with two members of the Pussy Riot group Tuesday, was at a bus stop Sunday when police approached him and asked for his identification, Popkov said. He gave them his passport but was detained. Noskovets arrived several minutes later, and Popkov said police took her away, too.

Khakim and Noskovets were intending to meet Sunday, but Popkov said he did not know if they planned to protest.

It's the second time in less than a week that both Khakim and Noskovets have been detained.

Khakim was given 30 hours of labor Monday for holding up a sign supporting another environmentalist who was recently imprisoned. The next day, he was picked up along with two members of Pussy Riot. All three eventually were released without charge.

Noskovets, a member of "Ecological Watch for Northern Caucasas," was picked up Monday. She was not charged, but was fined $15 because she did not have her passport.

The detainment of Khakim and Noskovets could be related to sentences that are to be handed down for eight protesters who were convicted of participating in mass riots and hitting policeman during an opposition rally in May 2012.

The eight were convicted Friday, but their sentencing was delayed until Monday â?? one day after the Sochi Olympics end.

Prosecutors are asking for sentences of up to six years for the eight: Sergei Krivov; Alexandra Naumova; Andrei Barabanov; Alexander Polikhovich; Artyom Savyolov; Stepan Zimin; Denis Lutskevich and Artyom Belousov. Most have been in custody since their arrests May 6, 2012, when a massive march to protest Vladimir Putin's third term as president ended in scuffles with police in Moscow's Bolotnaya Square.

Another defendant, convicted of similar charges as the eight, has already been sentenced to 4 Â½ years. Yet another was committed to a psychiatric hospital.
